    摘要： A digital broadcasting system and a data processing method are disclosed. Herein, additional encoding is performed on mobile service data, which are then transmitted, thereby providing robustness in the processed mobile service data, so that the mobile service data can respond more strongly against fast and frequent channel changes. The data processing method of a digital broadcast transmitting system includes the steps of forming a RS frame by grouping a plurality of mobile service data bytes that is being inputted, and performing error correction encoding in RS frame units, forming a super frame by grouping a plurality of the error correction encoded RS frame, performing row permutation in super frame units, and dividing the super frame back to RS frames, and dividing the RS frame into a plurality of data groups.

    摘要： A service multiplexer of a digital broadcasting system includes a null data generator, a mobile service multiplexer, a main service multiplexer, and a multiplexer. The null data generator may generate null data. The mobile service multiplexer may multiplex and output compression encoded mobile service data, additional data for a mobile service, and null data at a pre-determined first data rate. The main service multiplexer may multiplex and output compression encoded main service data and additional data for a main service at a pre-determined second data rate. The multiplexer may multiplex the output data of the main service multiplexer and the output data of the mobile service multiplexer at a pre-determined third data rate and transmitting the multiplexed data to at least one transmitter located at a remote position.

    摘要： A method of processing broadcast data includes performing RS (Reed-Solomon) encoding and CRC (Cyclic Redundancy Check) encoding on mobile service data to output an RS frame; dividing the RS frame into a plurality of portions; block processing data in one portion of the plurality of portions; mapping the block processed data in the one portion into at least one region of a data group that comprises a plurality of regions, and adding a first known data sequence, a plurality of second known data sequences, and a transmission parameter to the data group; and transmitting a transmission frame including the data group, wherein the transmission parameter is positioned between the first known data sequence and one of the plurality of second known data sequences, and the first known data sequence and the one of the plurality of second known data sequences differ from each other in length.
